I think that whatever our conclusions could be your patch is correct. I 
forgot to indicate the result-type, and I should have done that.
I forgot to indicate the result-type in every other use of sequence-get, 
so I probably should correct this and repost the extension. Then you 
guies could commiting it in the cvs of clocc, cmucl, sbcl ... ?
